Apps to Install and Uninstall Icons from Launchpad

I have found an application by a third party that installs in the System Preference file that allows you to Add or Delete any Icon from Launchpad with just a click.
I have installed the program and it works very good - no problems.
I also run NORTON Internet Security 5 for MAC and the program went though the filters and checks with NO problems.
Below is the link that takes you to the developer and download sight by a developer named Chaosspace.de
http://chaosspace.de/launchpad-control/
Good luck and I hope this help everyone, this problem is very frustrating!

Why?  In general this type of setup is handled by using standard Windows authentication.  Normal users cannot install/uninstall programs.  The problem solves itself.  You cannot technically prevent an admin from removing a program. 
It simply isn't possible.  As an admin I can remove the folder containing your program and it is effectively uninstalled.  I can manually remove any registry entries you create and it is uninstalled.  I can basically manually uninstall anything
that you install as an admin.

    I have repeatedly installed and uninstalled Microsoft Silverlight, I have followed every thing out there and uninstalled from various folders.  It still states the program is there and it won't run.  This is also happening with my coupon printer that word

    Copied from a page that helped me:
    I followed someone else's advice and found all the silverlight files in "INVISIBLE FILES".
    In the Finder, choose File > Find or press Command (⌘)-F.
    From the far-left pop-up menu (labeled “Kind”), choose Other.
    In the list of search attributes, select the “File invisible” checkbox, and then click OK.
    In the related menu, choose Invisible Items.
    once loaded go to folder Private
    then to folder VAR
    then folder db
    then folder Receipts
    scroll to any com.microsoft.silverlight item and delete. there are a bunch of them.
    close, restart and install silverlight.

  • I have recently tried to access my itunes account but am unable to.  I installed and uninstalled the new download several times.  I know I have a balance from itunes cards on my account as I received an email recently.  I have an ipod shuffle

    I have tried to access the itunes store by many different means.  I know I have account balance as I put in 2 gift cards back in March and have not used them all.  I recently installed and uninstalled itunes several times but I still cannot open it on my computer.  When plugging in my ipod shuffle it does not automatically load either although my computer says it's working correctly.

    Click on the "Start" button. Click "Run." Type the word "cmd" in the open box. When the DOS screen comes up, type "netsh winsock reset." Press "Enter." Type "exit" to close the DOS window and go back to Windows.

  • How do you remove an unwanted Steam icon from Launchpad?

    I found an answer to this question online after some extensive searching. The answer isn't on the Support Forums, so I thought I'd post a link to the page (to credit the author) and copy / paste the wording below. 
    You don't have to download any dirty third party apps to do this...thanks to Joe!
    FORCE REMOVING ICOMS FROM LAUNCHPAD
    http://joegardiner.co.uk/removing-icons-from-launchpad/
    The standard method for removing app icons from the Lion Launchpad is to hold the left mouse button [or old the Option / Alt key] over the app icon, wait for the cross to appear in the corner of the app icon, and then click it!
    In some cases however app icons can become orphaned, for example if you use on Steam on Mac, deleting local content to uninstall a game will not remove the game icon from Launchpad. This leaves you with an unusable orphaned icon that seems invincible and does not appear in the Application folder along with the rest of your apps.
    The solution is as follows…
    1. Open Launchpad, find the offending icon(s) and drag them to your normal dock.
    2. Right click on the icon that you dragged to your dock and choose ‘Show in Finder’.
    3. Now drag the icon(s) from the Finder windows that opens up into the Trash.
    4. Finally right click on the dock item(s) that you dragged originally and choose ‘Remove from dock’.
    Voila, the icons have disappeared from Launchpad and the annoying orphaned icons that seemed invincible have been thwarted.

    Maybe this is an issue I should consult my ISP about??
    No question about that. If you can "see" Travis's device, then he can likely "see" your Time Capsule.
    I'm just concerned that whomever the APExpress belongs to could be changing settings on my computer or Time Capsule that would cause the issues with me not being able to backup.
    Make sure that you have a Time Capsule base station password. Unless a user has that password, they might be able to "see" your Time Capsule, but they cannot access any of the data on the Time Capsule or change the settings.
    Open AirPort Utility, click on the Time Capsule and click Manual Setup
    Then, click the Time Capsule tab below the icons to see the device name and password for your device. Make sure that you have entered the password and confirmed. Click Update if you have made any changes.
    The message I get is "The backup was not performed because an error occurred while copying files to the backup disk.  The problem may be temporary.  Try again later to back up.  If the problem persists, use Disk Utility to repair your backup disk."
    I am not sure what this error means, because I cannot duplicate it here to test.
    If it were me, I would try this "fix".

  • Problem with installing and uninstalling applicati...

    hi all,
    I have a problem with installing or uninstalling apps on 808. When i try to install an application through Nokia suite or when trying to run the application file from the phone's memory the screen freezes and becomes unresponsive but the 3 phone buttons work just fine. I have to shut down the phone and the screen becomes responsive again. Anything available to help me wiith this situations as I cannot use any of the apps I have. Any help much appreciated.
    Regards
    Alex

    You are not alone. Im also having the same issue because we do alot of install and uninstall apps. This is the bad point of symbian. But I tired to install the latest FP2 it will be slightly abit smoother now. So you have the latest version now but did you tired to restore any backup yet? It might be the setting on when you restore that affect it. The feezing should be shorten on FP2 but it will still remain there depending on the type of apps from what I experience.
    I hope they will provide multiple function to uninstall apps since it will go through a long process to uninstall apps 1 by 1.
    Reason is because some apps will go through process like preparing install, process install, finalising install which take away your control for that few seconds or a minute instead runnning in background mode. Its not convenient to uninstall more apps.

  • How can I download itunes when I get the following errors...have installed and uninstalled a dozen times with various fixes...b noir for example and used Revo to clean up..ituneshelper did not install correctly error 7

    How can I download itunes when I get the following errors  ..ituneshelper did not install correctly error 7..I .have installed and uninstalled a dozen times with various fixes...b noir for example and used Revo to clean up.
    This has been a problem for 6 weeks now, I retry when I have time and patience and use my other laptop which is also Windows 7 and runs with no problem.
    Every attempt fails when all seems fine on the desktop and I try to log on to Itunes I get the errors.
    Any help greatly appreciated.

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features(Later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support (If this won't uninstall press on)
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    See also HT1925: Removing and Reinstalling iTunes for Windows XP or HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
    Should you get the error iTunes.exe - Entry Point Not Found after the above reinstall then copy QTMovieWin.dll from:
    C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    and paste into:
    C:\Program Files (x86)\iTunes
    The above paths would be for a 64-bit machine. Hopefully the same fix with the " (x86)" omitted would work on 32-bit systems with the same error.

    I had the older version of ITunes and then it disappeared.  When I try to install the new version, I keep getting "unable to install ITunes, Error 7 (windows error 5) message.  I have repeatedly installed and uninstalled iTunes without luck.  Any chance of actually getting this on Windows 8.1 or not?  I am assuming I also lost my library during this.

  • Remove collapse and expand icons from tray header

    Hi all
    Is it possible in any way to remove the collapse and expand icons from the tray header, and have the menu icon aligned with the end of the underline?
    Uploading a transparent gif does'n help, because the collaps and expand icon has the same width and heigh as the menu icon. Thus if I upload a transparent gif, and the width of the icons is set to 14px, the menu icon is not aligned with the line which underlines the whole header. There is 14px of blank / transparent.
    Removing the menu icon is easy, all I have to do is deselect all the 'show xxx' options in the iView editor.
    It should be possible to remove the collaps and expand icons, and still be able make it look good.
    Has anyone else had this problem??

    Amit,
    Thank you for replying twice, much appreciated.
    I am sorry for my late response. Thank you for the tip, but as far as I can see this is related to SP 15. We are currently on SP13. I should have of course have mentioned which SP in my problemdescription, and had we been on SP 15 I would have tried this solution.
    Anyway, points rewarded for being helpful.
    Markus,
    I did not find a solution for our problem. However during this summer our customers have decided that it was not very important to remove this icon, so I have left it. I hope the suggestions from Amit and Prem can give you some tips if you have a similar problem.
    Prem,
    as far as I understand you are suggesting to override the jsp for the iViews-trays, like you suggested for the detailed navigation? Anyway, it sounds like a good idea, and worth a try. But, as I mentioned above, we have deceided not to remove the icon. However, it sounds interesting, and I would like to investigate these possibilities when I have the time. points rewarded for being helpful
    Kind regards,
    Reidun

  • Drag and drop icons from onside of the split pane to the other side.

    Hello All,
    I am tring to write a program where i can drag and drop icons from the left side of the split pane to the right side. I have to draw a network on the right side of the split pane from the icons provided on the left side. Putting the icons on the labels donot work as i would like to drag multiple icons from the left side and drop them on the right side. CAn anyone please help me with this.
    Thanks in advance
    smitha

    The other option besides the drag_n_drop support
    http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.htmlis to make up something on your own. You could use a glasspane (see JRootPane api for overview) as mentioned in the tutorial.
    Here's another variation using an OverlayLayout. One advantage of this approach is that you can localize the overlay component and avoid some work.
